Hey mikedc813,
If something can be learned from my experience (as well as I can remember it, at least. This was all with the help of my boss; I was a 21 year-old rookie): submitted to Green Journal in Jan 2010. Got a request for more info at the end of the Spring 2010. Submitted the info 1 month after that, and the paper was published Aug 2011. I thought that my experience was exceptionally long (blamed it on the fact that we were refuting a paper the Green Journal had recently published), but perhaps it was the norm. It's a shame, considering that many people view it as the 2nd best RadOnc Journal. For reference: my team's Red Journal paper took about 8 months from start to finish (it needed only very minor revising). 3rd paper in Physics in Medicine and Biology took a year from start to finish, and 4th in TCRT took a year and a half. Hope that helps. Good luck!
